I woke up one morning and sighed out "man that was just a dream, what the hell". What beats me is the distinction between a dream and reality. You will actually know that it was a dream once you wake up from it. The big question is: how could you know that you are actually in a dream where you don't even have the idea that dreams really exist when you are in one. Although a lot of unrealistic events happen in your mind while you are asleep and it is still impossible for you to say that it is unreal. Well perhaps there is a big question behind this phenomenon.

 I read from one article that dreaming compensates for the wishes of an individual like say for example, you are really frustrated in achieving something or you can't get something you really want. The dream will try and make it real for you; there is also a possibility for you forgetting what you want because of that dream. Dreams also have a very good function to "clean" your mind; it is somewhat similar to defragmenting your hard drives at the same time creating ideas for you which are quite impossible to visualize while you are conscious. Indeed dreams are special and that reality would be too much to handle without it.
